A Preferable Interconnect Solution for SFP+ Applications–SFP+ AOC Assemblies

by www.fiber-mart.com

Dramatically reducing 10G interconnectivity costs, the 10G SFP+ cables can provide inexpensive and reliable 10G speed connections using either SFP+ copper cables or SFP+ active optical cables (AOCs). SFP+ AOC is a cabling technology that accepts the same electrical inputs as a traditional copper cable. It uses optical fiber and electrical-optical conversion on the cable ends to improve speed and data transmission distance of the cable while not sacrificing compatibility with standard electrical interfaces. Nowadays, SFP+ AOC has been a preferable interconnect solution for SFP+ applications. Before choosing it for your applications, you need to have a basic understanding about it.

 

Description

AOC consists of multimode optical fiber, fiber optic transceivers, control chip and modules. SFP+ to SFP+ active optical cable is composed of SFP+ optical transceivers in both ends and fiber optic cable in between. This integrated optical module solution removes the complicated optical fiber interface and brings friendly and intuitive electrical-to-electrical interface to users. SFP+ AOC is designed to meet the requirements of high speed, high density and low power consumption for applications in today’s data centers via optical fiber wire. SFP+ AOC is compliant to industrial standard SFP MSA and provides high performance SFP+ interfaces, supporting 10Gb/s bi-directional operation. The demand for more bandwidth for data center is challenging interconnect technologies like Ethernet, Infiniband, and Fibre Channel. SFP+ AOC is one of the best solutions to solve this problem. The image below shows a Cisco SFP-10G-AOC10M compatible SFP+ to SFP+ AOC. It is a 10Gb/s, hot pluggable active optical cable for Ethernet data transmission.

 

Advantages

Compared to SFP+ copper cables for data transmission, SFP+ AOCs provide more advantages, as shown below:

 

Longer reach

Lower weight and tighter bend radius enable simpler cable management

Thinner cables allows better airflow for cooling

Lower power consumption

No need for power-hungry conditioning ICs on the host board

 

Application

SFP+ active optical cable is a 10Gbps and cost effective solution for 10G Ethernet (10GbE) applications. With industry-leading VCSEL technology and an advanced new light engine design, the SFP+ AOC assemblies are ideal for high-performance computing clusters, 10G Ethernet applications (10GbE), 4G and 8G Fiber Channel applications (4GFC/8GFC), 1x InfiniBand QDR, DDR, SDR, servers, switches, storage and network interfacing applications.
